Wanting to switch fish over to new tank

[Kfactor]

Hi all I just have a few questions I’m wanting to switch over my fish to my new setup soon . In my old tank I have red flat worms / tub worms This will be a dumb question but can the fish carry coral pest or anything from the old
Tank ? There is also a few corals I want to keep but those will be going in to a qt tank Forsure for a long time to get rid of any pest on them and still not sure I want to bring any corals over from the old tank

I don’t think they will, you could always do a freshwater dip (pH corrected) on the way over to your new tank.. although some fish tolerate it better than others
